Snow Creek Road MP 0.84 Culvert Upsizing

Jefferson County Public Works was awarded $1.16 million funding from FEMA’s Hazard Mitigation Grant Program and $500,000 through a Washington State Public Works Board construction loan to replace the Snow Creek Road, milepost 0.84, culvert. The current culvert was constructed in 1968 where the road crosses a 30-45 foot deep canyon/stream. The bottom of the 24-inch diameter, 190 ft long, corrugated metal pipe had rusted through undermining the culvert outlet and causing segments to drop off. The culvert was also originally installed under poorly compacted and steeply sloping fill material. It was undersized and had repeatedly become blocked with debris during storm events causing a dam that threatened to wash out the road fill. Past flood events had required the road crew to “tend” the culvert for hours using inlet poles and grapples to unplug it and keep it flowing. If the pipe were to plug and cause water to crest over the top of the road, it is likely the road fill would have collapsed, sending a torrent of 14,000 cubic yards of liquefied “mud” down the stream and hillside into Lake Leland.

The project was put out for bid in February 2023 and the contract was awarded to Bruch and Bruch Construction of Port Angeles.  

The culvert was replaced with a new 72-inch diameter culvert with a 75-year design life. The greatly increased diameter will easily handle the necessary water and debris passage, eliminating the threat of washout, and allowing for the future relining of the pipe at a significantly reduced cost.

Following installation of the new culvert, the roadway embankment was reconstructed, the roadway re-paved, slopes revegetated, and the road was re-opened to traffic on August 30, 2023.  Guardrail was installed in October and project construction was complete as of October 19, 2023.  

Public Works thanks Snow Creek Road residents and other road users for their patience during the road closure, and their cooperation in completing this important project.
